Abstract

This invention provides a product information management device that generates a product master database updated with the latest information. It includes: a storage means for each product, which associates and stores product identification information, first item information, and second item information; a means for selecting product identification information and first item information from an image medium using image recognition processing; a means for accessing a database stored on an external device and selecting product identification information and second item information; a means for determining whether the selected first and second item information associated with product identification information is consistent with the first and second item information associated with product identification information stored in the storage means; and, if inconsistent, notifying the result and replacing the first and second item information associated with product identification information stored in the storage means with the selected first and second item information associated with product identification information.

Claims

1. A product information management device, characterized by comprising: a product information storage means, for each product, associating and storing product identification information, first item identification information and its value, and second item identification information and its value; an image information selection means, by means of image recognition processing, selecting from an image medium a combination of product identification information and the first item identification information and its value associated with the product; a database information selection means, accessing a database stored on an external device, and selecting from the database a combination of product identification information and the second item identification information and its value; and a first determination means, determining whether the combination of the first item identification information and its value associated with the product identification information obtained by the image information selection means is consistent with the combination of the first item identification information and its value associated with the product identification information stored in the product information storage means; The second determination means determines whether the combination of the second item identification information and its item value, which is obtained by the database information selection means and associated with the product identification information, is consistent with the combination of the second item identification information and its item value, which is stored by the product information storage means and associated with the product identification information. The first product information correction means, if the first determination means determines that they are inconsistent, reports the result and replaces the item value of the first item identification information, which is stored by the product information storage means and associated with the product identification information, with the item value of the first item identification information, which is obtained by the image information selection means and associated with the product identification information. The second product information correction means, if the second determination means determines that they are inconsistent, reports the result and replaces the item value of the second item identification information, which is stored by the product information storage means and associated with the product identification information, with the item value of the second item identification information, which is obtained by the database information selection means and associated with the product identification information.

2. A product information management method, performed by a computer equipped with a product information storage means; the product information storage means associates and stores product identification information, first item identification information and its value, and second item identification information and its value for each product; the product information management method is characterized by comprising the following steps: using an image information selection means, through image recognition processing, selecting a combination of product identification information and the first item identification information and its value associated with a product from an image medium; using a database information selection means, accessing a database stored on an external device, selecting a combination of product identification information and the second item identification information and its value from the database; using a first determination means, determining whether the combination of the first item identification information and its value associated with the product identification information obtained by the image information selection means is consistent with the combination of the first item identification information and its value associated with the product identification information stored in the product information storage means; The second determination means determines whether the combination of the second item identification information and its item value, which is obtained by the database information selection means and associated with the product identification information, is consistent with the combination of the second item identification information and its item value, which is stored by the product information storage means and associated with the product identification information. The first product information correction means, if the first determination means determines that there is a discrepancy, reports the result and replaces the item value of the first item identification information, which is stored by the product information storage means and associated with the product identification information, with the item value of the first item identification information, which is obtained by the image information selection means and associated with the product identification information. The second product information correction means, if the second determination means determines that there is a discrepancy, reports the result and replaces the item value of the second item identification information, which is stored by the product information storage means and associated with the product identification information, with the item value of the second item identification information, which is obtained by the database information selection means and associated with the product identification information.

3. A product information management program for enabling a computer to implement the product information management method of request item 2.
